To @ZZ zzz/1,0712, it may concern:

Be it known that' I, DWIGHT B. SUPER, a citizen of the United States, residing at Flint, in the county of Genesee and State of Michigan, have invented certain new and useful Improvenients in Churns, of which the following is a full, clear, and exact description.

This invention relates to that class ofehurns in which the body containing the iiuid is rotated upon a iixed axis in order to produce The invention consists in a cover for-such and similar churns, and in details of construe'- tion, all as hereinafter more particularly set forth and claimed.

In the accompanying drawings,in the several figures of which like parts are similarly designated, Figure l is a side elevation. Fig. 2 is a top view. Fig. 3 is a cross-section of the top ofthe body in the line of the length of the clamping-arms. Fig. 4 is a similar section at right angles to the last-named section. Fig. 5 is a detail of the clampingarm, holdingplates, or socket; and Fig. 6 is a perspective of part of the cover-receiving head or rim'and one of the catches for the clamping-arms.

A suitable platform, a, from which rise parallcl vertical posts b, is prepared to receive the churn-body o, which last is here shown as a cask or barrel, and it maybe of any approved construction and size or sizes and material. The churn-body in this instance is shown provided with gudgeons orjournals d d, suitably affixed to opposite sides of the body about midway of its length and in the same horizontal plane, and resting and turning in bear- On one of these journals is secured a pinion, e, which meshes with an internally-toothed driving-wheel, f, the latter being secured to a journal, g, made fast to one of the posts b, and also provided with a crank or handle, h, for rotating said wheel by hand, though, obviously, a' bandwheel may be connected to the said drivingwheel for connecting the churn with means for driving it by power, using ordinary means and power to this end.

fer to be in the proportion of about one to three, so as to get increased motion at a small expenditure of power. j

The chief feature of my invent-ion I will now proceed to set forth.

The bottom of the churn-body may be of the construction commonly employed in heading barrels. l

The fixed part of the cover is composed of a metallic annular rim, k, dat on the under side and beveled on the upper side, so as to t into the chine, the same as an ordinary barrel-head, and secured therein by the hoops, as usual in heading barrels. This rim is provided with an internal rabbeted lip, Z. The removable cover m, of wood by preference, is provided on its underside with a rabbet, a, in which is tted a packing, o, of cork or othermaterial orsub sta-nce of a like yielding or conforming quality. This packed edge ofthe cover engages the rabbeted lip of the annular rim, so as to make a tight joint therewith. The edge of the cover is bound by an angle-plate,`p, which projects over and keeps the packing o in place, besides strengthening and preserving the edge of such cover. In the center of the cover is arranged a metallic internally screw-threaded socket, q, into which is litted a screw-post, i', having the shoulder r', and rising above the latter, the diametriCally-reduced round journal a, which is continued as a squared portion, r3, and terminates in the screw-threaded portion r4. A plate, s, rests upon the shoulder fr of the screw-post r, and this plate has a diametric socket, s', which receives the ends of the cover-clamping arms t, which, when in place in the said socketed plate, are retained therein by a plate, s?, having the socket s, to*Y l match and cover the socketed plate s. The plates s and s?, with the arms t in place therein, vare held together, and the post 'r rotated so as to raise and lower -it in the screw-socket q, by means of a handle, a, secured to the squared portion r3 of the :post by a nut, n', on the portion rt, it being obvious that rotating the handle will rotate the screw-post, and hence raise and lower it in its socket, and consequently raise and lower the arms t t. These armst I, extend diametricall y across the cover and work in guides o, rising from the angle-plate p, and

IOO f extend slightly beyond the cover. They arev held to place in the said guides byloops fw, secured to the plate p, and their outer ends are constructed to engage right and left catches m, fast on the annular rim 7c and rising from the top thereof. It will be understood that by raising the post r, the arms are loosened from the catches, and by then giving the cover a partial rotation the said arms escape sidewise from the catches and the cover may be removed. By replacing the cover and inserting the arms again in the catches, and then rotating the screw-post, so as to lower it into its socket q, the arms are forced home into the catches, and the guide o, acting as iulcrum for said arms, the continued downward movef ment of the screw-post will cause the arms to act as levers with the catches as the weight, and hence bind the cover tightly to its seat in the rim k. rI`he action ol' the parts r, s, s2, and u upon the arms t is practically that ot' an eccentric.

l A glazed opening, y, may be made in the cover to inspect the interior of the body, and hence note the progress of the churning. Obviously this closure may be applied to vessels generally, and hence my invention is notlimited to churns.

Vhat I cla-im ism- 1. A body, c, provided with an annular rabbeted rim secured in the chine like a barrelhead, a cover provided with a packed edge to iit in said annular rim, and cover-clamping arms arranged upon said cover and engaging catches on the said rim, combined with a screw-threaded socket in said cover, a rotary threaded post arranged in said socket, socketplates 011 said post receiving the said clamping-arms, and a device to rotate said post, substantially as described.

2. The covei` provided with a scre\\thread ed socket, combined with a rotary threaded post, r, arms t, socket-plates s s2 on said post receiving the said arms, and an operating-handle for said post, substantially as described.

3. The cover, a screw-threaded socket therein, a rotary threaded post in said socket, socket-plates on said post, arms seated in said plates, and an operating-handle for said post, combined with guides for said arms, a rim, and catches on said rim with which said arms are engaged, substantially as described.

In testimony whereof I have hereunto set my hand this 7th day of June, A. D. 1886.
